Scattershield Modification

Parts Checklist

Tools required

We like to install scattershields in our personal rides. Since our feet extend past the clutch plate, we like to have something more than a cast aluminum bellhousing between our legs and the spinning flywheel/clutch setup.

This information is provided only to let you know what we have tried and found mentally comforting. Anyone contemplating modifying their own scattershield should see the bottom of this page for important safety tips.

Below, a trimmed 427 scattershield installed in a running Kirkham 427:


Here are some pictures of the two areas of the 427 Scattershield we trim:

The additional cross-hatched area is optional, depending on how into metal removal we are at the moment. Generally, we don't bother.

Frame Clearance


Ground Clearance

The untrimmed scattershield will hang below the frame rails, increasing air and asphalt resistance. It also makes ramp loading of the car difficult. The trimmed part is flat across the bottom.


Disclaimer: As with so many other things in life, what you do here is at your own risk. Kirkham Motorsports is providing this information only to let people know what we do with our own personal stuff. Kirkham Motorsports isn't responsible if you have problems before, during or after this warranty-voiding modification.

Modifying your scattershield may kill, injure, harm, upset or otherwise cause problems to you, passers by, pets, government officials, race sanctioning bodies and others. Please check local laws, race sanctioning bodies, and anyone else who might have a competent opinion before undertaking the modifications listed above.

It is likely you will use dangerous tools to perform the above modifications. Please insure that all tool safety equipment is in place before attempting any modifications. For your own safety, it would be best to hire someone competent and experienced to modify your scattershield for you.

Lakewood makes a very fine scattershield which can be installed after trimming. On the down side, the modifications on this page will probably void whatever warranty your scattershield may have had. Furthermore, common sense says any cuts made to the scattershield will probably weaken it, though it should still be better than a cast aluminum bellhousing (which we wouldn't ever use). Obviously, any modifications you make to the scattershield are at your own risk.
